The famous hall “Halle der Circe” is located at the end
of the highest-lying touristic cave in the world (2100 m alt.), which
can be reached only by experienced cavers. With proper lighting the
permanent ice in the hall shines in beautiful blue tones, which add
enchantment atmosphere to the frozen hall.

Spectacular Photographs from 2015 Nat Geo Traveler Photo Contest

The late afternoon sun shines down on the Gorner Glacier
above the Swiss town of Zermatt. The radiant heat offers enough warmth
to let algae grow in the snow and cast a pink hue with their growth. The
seasonal weather also causes the ice to crack and melt, which causes
rivers and waterfalls to form from the runoff and cascade down the giant
rock face of Monte Rosa Massif.

The little tarsier, nicely nestled in a leaf, suddenly
opens its eyes! They are nocturnal so what a surprise. These tiny
primates (3 to 6 inches) are found only in the Philippines and most of
them are in sanctuaries. This one was in a sanctuary in Bohol Island.

Captured in Kruger National Park in South Africa, this
lion was one of four coalition males that had made an elephant kill
during the night. For four days they fed on their prey, and this
beautiful male was ready for a nap after filling his belly.

It was minutes before sunset in Masai Mara reservation
and moments before we arrive at the camp where I saw hundreds of wild
beast heading toward the river. one of the wild beasts was still and
staring at me. A shot with a slow shutter produced this photo.

The Rock restaurant just off shore in Zanzibar. As the
sun set, I was taking photos of The Rock before going out there to have
dinner. As the light levels dropped, the light came on in the restaurant
and I knew I had my shot.

break during the 2015 Caribbean Cup of Freediving in Roatan, Honduras.
Every time I look at this photo it relaxes me and makes me wonder about
how these athletes can reach depths of 300ft. and hold their breath for
upwards of 4 minutes.
